To put it to anticipate: I've had before, to purchase this product here as well, but after our Expert of local retailer discounted exactly this part of 379,00 to 199,00 Euro unbeatable, the choice was clear. But now to the device itself: I now have to test it extensively for 2 weeks in use and could it in this my vacation time. The Bluetooth connection to all devices work properly. Quick connected and ready to go. Playback via radio is only minimally worse than a direct connection in the Dock (Caution: Dock for Apple Devices, logo!). However, no difference I could see if the Fidelio in mains or battery operation. The sound is for such a relatively small and handy device more than remarkable. The bass is always (regardless of volume!) Dry, clear and completely undistorted. The centers come clearly into their own and the tweeter make a more than decent job. The Fidelio DS8550 / 10 adapts namely digitally to all possible circumstances in! Something that is otherwise known only in the most significant equipment levels! Thanks to the very good battery (4.5 hours at fairly loud use on a barbecue) the docking station is completely disabled friendly. And the best iPhone and iPod are also on battery power charged (Then of course shortened battery life, logical.) The iPad, however, only charges on AC power and when the screen is off As others have already written here, the Fidelio does not hide behind a lot more expensive devices. Overall, the device an absolute-quality, sophisticated look without being intrusive but makes visually. As it were an eye-catching style! Conclusion: For the price demanded here is what gets very, very fine and high-quality processed. Strong buy recommendation!
